Description
Technical field
The utility model belongs to solar heat pipe technical field, relates to a kind of solar heat pipe, particularly a kind of Horizontal heat pipe for solar thermal collector.
Background technology
At present, for the heat pipe type heat collector in solar water heating system, there is a lot of limitation in the two-phase closed type hot siphon that market uses and conventional levels heat pipe in use.Two-phase closed type hot siphon, its inside does not have liquid-sucking core, and manufacture craft is simple, and the work of working medium, just by the effect of gravity, completes the whole course of work, realizes the heat absorption heat release of heat pipe.But gravity exists directionality, therefore only realize the two-phase closed type hot siphon of working medium circulation by Action of Gravity Field, certain inclination angle must be met installing, level cannot be realized and run, there is larger limitation.At present conventional conventional levels heat pipe, its internal working medium relies on the effect of internal capillary power to complete the backflow of working fluid condenses liquid and uniform, realizes the heat absorption exothermic process of heat pipe.Directionality is there is not in conventional levels heat pipe in use, level can be realized run, but owing to have employed liquid sucting core structure, cause its structure comparatively complicated, manufacture craft is loaded down with trivial details, simultaneously liquid sucting core structure have impact on its steam cavity diameter, causes its through-put power to reduce, and more difficultly meets actual production demand.
Utility model content
Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, a kind of Horizontal heat pipe for solar thermal collector is provided, material can be saved, also can strengthen the evaporation and condensation process of inside heat pipe working medium, increase the through-put power of heat pipe, can level install, operating efficiency is high, is applicable to remotely transferring under small inclination or level.
In order to solve above technical problem, the utility model provides a kind of Horizontal heat pipe for solar thermal collector, comprise be interconnected evaporator section, condensation segment and adiabatic section, described adiabatic section is between evaporator section and condensation segment, described evaporator section is divided into supervisor and arm two pipelines in the one end near adiabatic section, and wherein supervisor is liquid return tube, and described arm is vapor uptake, described supervisor and arm meet at adiabatic section, are filled with heat-conducting work medium in described Horizontal heat pipe.
Like this, heat pipe is made abnormally-structured, evaporator section is the isocon pattern be formed by connecting by a straight length and a bend loss, supervisor and arm form shunting in junction, namely most steam upwards flows along arm, and only have seldom part to continue to flow into adiabatic section from supervisor, so just effectively reduce the rolling action of steam to withdrawing fluid, reduce the resistance that in heat pipe, steam and liquid refrigerant flow, enhance the evaporation and condensation process of inside heat pipe working medium, increase the through-put power of heat pipe under small inclination and level, solve solar thermal collector heat pipe and monistic defect is installed.
The technical scheme that the utility model limits further is: the aforesaid Horizontal heat pipe for solar thermal collector, arm in described evaporator section is oppositely arranged on the top of described supervisor, and described supervisor's internal diameter is greater than a described bore, this ensures that there liquid to flow in supervisor all the time, steam then can rise in arm, forms steam and is separated with the effective of liquid.
The aforesaid Horizontal heat pipe for solar thermal collector, described condensation segment is equal with adiabatic section internal diameter, and is greater than the summation of the internal diameter of supervisor and arm in evaporator section.
Further, the aforesaid Horizontal heat pipe for solar thermal collector, the supervisor's inwall in described evaporator section is covered with liquid-sucking core, and described liquid-sucking core is silk screen and/or groove.
The aforesaid Horizontal heat pipe for solar thermal collector, shell is copper, silver, aluminium, carbon steel or stainless steel, and the working medium filled in described shell and shell is compatible.
The beneficial effects of the utility model are: Horizontal heat pipe of the present utility model enhances the evaporation and condensation process of inside heat pipe working medium, both increased the through-put power of heat pipe under small inclination and level, and solved again solar thermal collector and monistic defect is installed.Heat pipe of the present utility model can level not use by angle restriction, can vertically use again; And wide application, can be used alone in flat-plate collector, use together with coordinating with glass tube with vacuum again.Heat pipe structure of the present utility model is simple, easy to make; Heat pipe temperature control ability, heat-transfer capability are all better than at present conventional two-phase closed type hot siphon and conventional levels heat pipe, can meet the demand of solar thermal collector and system under various condition.

Detailed description of the invention
embodiment 1
The present embodiment provides a kind of Horizontal heat pipe for solar thermal collector, structure as shown in Figure 1, comprise evaporator section 1, condensation segment 2 and adiabatic section 3, adiabatic section 3 is between evaporator section and condensation segment, evaporator section 1 is divided into two pipelines in the part near adiabatic section 3, and being wherein responsible for 4 is liquid return tube, and arm 5 is vapor uptake, supervisor 4 and arm 5 meet at adiabatic section, are filled with a certain amount of heat-conducting work medium in Horizontal heat pipe; In evaporator section 1, the relative position of arm 5 is upper, supervisor 4 relative position under; Condensation segment 2 is equal with adiabatic section internal diameter, and is greater than the summation of supervisor 4 and arm 5 internal diameter; Evaporator section 1 is responsible on 4 inwalls and is covered with silk screen liquid-sucking core; Heat pipe package is stainless steel, and the working medium filled in shell and shell is compatible.
The operation principle of the Horizontal heat pipe for solar thermal collector of the present embodiment is as follows: the heat obtained from thermal source passes to inner working medium by supervisor 4 tube wall of heat pipe evaporator section 1, vaporization after working medium heat absorption, the steam produced flows to the porch of arm 5 from the supervisor 4 of evaporator section 1, through shunting, most steam flows into arm 5 and finally flows into condensation segment 2; Small part steam flows into condensation segment 2 from supervisor 4, and the vapour-liquid interface in condensation segment 2 condenses; Heat passes to low-temperature receiver from vapour-liquid interface by liquid refrigerant and tube wall; In liquid-sucking core inside because capillary force effect makes condensed working medium be back to evaporator section 1 along supervisor 4.Hydraulic fluid absorbs heat at evaporator section 1 from thermal source and vaporizes, and so just define a circulation, the heat of thermal source is constantly passed to low-temperature receiver far away by hydraulic fluid.
Above embodiment is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection domain.
